||r/w||input data to be parsed for frames.|
||r/w||a combination of input and output
||r/w||media specific offset of input frame Note that a converter may have a different one on the frame’s buffer.|
||r/w||subclass can set this to indicates the metadata overhead for the given frame, which is then used to enable more accurate bitrate computations. If this is -1, it is assumed that this frame should be skipped in bitrate calculation.|
Frame (context) data passed to each frame parsing virtual methods. In addition to providing the data to be checked for a valid frame or an already identified frame, it conveys additional metadata or control information from and to the subclass w.r.t. the particular frame in question (rather than global parameters). Some of these may apply to each parsing stage, others only to some a particular one. These parameters are effectively zeroed at start of each frame’s processing, i.e. parsing virtual method invocation sequence.
new(buffer, flags, overhead)¶
Parameters: Returns: Return type:
Allocates a new
GstBase.BaseParseFrame. This function is mainly for bindings, elements written in C should usually allocate the frame on the stack and then use
GstBase.BaseParseFrame.init() to initialise it.
Frees the provided self.
GstBase.BaseParseFrameto initial state. Currently this means all public fields are zero-ed and a private flag is set to make sure
GstBase.BaseParseFrame.free() only frees the contents but not the actual frame. Use this function to initialise a
GstBase.BaseParseFrameallocated on the stack.
